Set DPKG_FRONTEND_LOCKED when running {pre,post}-invoke scripts

2018-10-05T10:45:47Z

Some post-invoke scripts install packages, which fails because the environment variable is not set. This sets the variable for all three kinds of scripts {pre,post-}invoke and pre-install-pkgs, but we will only allow post-invoke at a later time. Gbp-Dch: full

Support multiple keyrings in sources.list Signed-By

2018-09-11T11:16:11Z

A user can specify multiple fingerprints for a while now, so its seems counter-intuitive to support only one keyring, especially if this isn't really checked or enforced and while unlikely mixtures of both should work properly, too, instead of a kinda random behaviour.

Use a steady clock source for progress reporting

2018-05-28T15:59:35Z

Clock changes while apt is running can result in strange reports confusing (and amusing) users. Sadly, to keep the ABI for now the code is a bit more ugly than it would need to be.

don't try SRV requests based on IP addresses

IP addresses are by definition not a domain so in the best case the requests will just fail; we can do better than that on our own.

zstd: Implement support for multi-frame files

2018-04-13T21:15:06Z

This implements support for multi frame files while keeping error checking for unexpected EOF working correctly. Files with multiple frames are generated by pzstd, for example.

Implement compression level handling for zstd

2018-04-13T21:15:06Z

This is a simplified variant of the code for xz, adapted to support multiple digit integers.
